A machining center comprising two independent carriages (14', 14'') supported so that they can slide along respective longitudinal translation axes (X', X'') by two parallel horizontal rails (16a, 16b) which are fixed in a raised position to a supporting structure (12). The carriages (14', 14'') support respective machining heads (22', 22'') which can move along two respective translation axes (Y', Y'', Z', Z''). The machining heads (22', 22'') support respective tool holding spindles (28', 28'') arranged with a vertical axis. At least one workpiece holding table (34', 34'') is supported at the base (30', 30'') of the supporting structure (12) in a rotatable manner about a first horizontal and transverse rotation axis (Yr', Yr'') and about a second rotation axis (Hr', Hr'') which is perpendicular to the first one. Two mechanized tool magazines (36', 36'') are supported at the opposite longitudinal ends of the supporting structure (12) and are accessible by the spindles (28', 28'').

The present application relates to a multi-axis machining center provided with a mechanized tool magazine. The machining center comprises two independent carriages supported by two parallel horizontal rails fixed in raised position to a support structure so that they can slide along respective longitudinal translation axes. The carriages support respective machining heads movable along two corresponding translation axes. The machining heads support respective tool holding spindles arranged with a vertical axis. At least one workpiece holding table is supported at a base of the support structure in a manner rotatable about a first horizontal and transversal rotation axis and about a second rotation axis vertical to the first rotation axis. Two mechanized tool magazines are supported at opposite longitudinal ends of the support structure and are usable by the spindles.

This invention provides a tool changing device that prevents breakage of cutting tools and damage to the flange when mounting cutting tools with different cutting thicknesses on a tool mounting base. The tool changing device used in a cutting apparatus includes: a holding part that detachably holds one side of the cutting tool; a moving part that moves the holding part, holding the cutting tool, relative to the spindle in the axial direction of the spindle, positioning the holding part at least at a mounting position where the other side of the cutting tool, located opposite to one side, is at least a predetermined distance from the flange of the tool mounting base, and at a disengaged position where the cutting tool is away from the tool mounting base; and a thickness information acquiring part that acquires information about the thickness of the cutting tool, adjusting the mounting position of the holding part based on the thickness of the cutting tool acquired by the thickness information acquiring part.

The invention relates to a tool turret, provided in particular for use in a machine tool and for an automated tool-change process, it being possible, in at least one workstation (7) of a pivotable tool plate (5), for a holder (9), provided for receiving a machining tool (15), to be releasably fixed in each case to the tool plate (5) by means of a clamping device (31) associated with the relevant workstation (7), it being possible for the relevant clamping device (31) to be activated or deactivated in an adjustment position (57), which differs from the working position (11) of the tool plate (5), while leaving the holder (9) on the tool plate (5), and, in a change position of the tool plate (5), which differs from the working position (11) and the adjustment position (57), the clamping device (31) in question releasing the holder (9) such that said holder can be removed from the tool plate (5) and can be replaced by a different holder (9) that is to be introduced.
